Abstract

The embodiment of the invention discloses a distributed retrieval method, device and system, computer equipment and a storage medium, and belongs to the distributed technical field. According to the embodiment of the invention, the retrieval request forwarded by the access node can be received, the matching feature matched with the to-be-detected feature is searched in the at least two video memory blocks, the video memory blocks are physical storage units with fixed lengths, the retrieval result is returned to the access node, and the retrieval result is used for indicating the feature matched with the to-be-detected feature. According to the embodiment of the invention, the retrieval node comprises at least two video memory blocks; a cache space is distributed between at least two videomemory blocks by adopting a block chain type structure; according to the method and the device, the characteristics can be continuously stored in the video memory block, so that the problem of data discretization caused by storage holes due to deletion in related technologies is solved, the matching and to-be-detected characteristic efficiency is improved when the characteristics are subjected toparallel comparison, and the performance of a distributed retrieval system is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of distributed technologies, and in particular to a distributed retrieval method, device, system, computer equipment, and storage medium. Background technique [0002] With a large number of images uploaded by users of social applications, a large amount of image data needs to be stored in the cloud. In one application scenario, image data needs to extract features and save the image features. [0003] In related technologies, the image retrieval technology can obtain matching features that match the features to be detected from many image features. In this technology, the feature to be detected will be compared with many image features one by one in batches until the retrieval result matching the feature is obtained. [0004] Since the related art uses an array structure to store image features, when features in the array are deleted, there will be data holes in the array, resulting in a...
